Direct synthesis of 2,3,5-trichloro-4,4-dimethoxy-and 2,5-dichloro-3,4,4-trimethoxycyclopent-2-en-1-ones from hexachlorocyclopentadiene and some aspects of their reactivity
摘要:
2,3,5-Trichloro-4,4-dimethoxy-and 2,5-dichloro-3,4,4-trimethoxycyclopent-2-en-1-ones were synthesized directly by treatment of hexachlorocyclopentadiene with methanol in the presence of potassium hydroxide at room temperature or on heating and subsequent acidification of the reaction mixture. Reactions of 2,3,5-trichloro-4,4-dimethoxycyclopent-2-en-1-one with some reducing agents and nucleophiles were studied.
